Once you have connected the pump to your plumbing system plug the pump into the electrical supply check that the pump is being connected the the required voltage

The pump should behaves as follows:

• If the hydraulic circuit upstream from the pump has a pressure higher than CUT-IN, the pump motor does not start.

• If the circuit is not under pressure (P<CUT-IN), the pump motor is started and the pump will run.

• If the hydraulic circuit goes under pressure (P>CUT-IN) and there is no flow, for example because all the faucets are closed, the pump switches off after 10 seconds : the pump is primed.

• If there is no flow or pressure for 20 seconds (P<CUT-IN), the pump goes into DRYRUN alarm and is switched off: the pump is not primed.

• Finally, if there is flow because faucets are open, the pump is primed and runs normally.

If no pressure and flow is detected during normal operation (or during pump start-up) for 20 seconds, the pump will go into DRYRUN alarm and the pump will switch off.

The pump control electronics will try to restart the pump until the pump is able to create flow and pressure.

These restart attempts will be scheduled as follows:

• From the 1st to the 48th attempt: 1 restart every 30 minutes for 20 seconds each

• From the 49th attempt: 1 restart every 24 hours for 20 seconds each

The DRYRUN alarm can be reset manually: if after this reset the pump still does not detect flow and pressure, attempts will last 20 seconds.

The pump electronics have an anti-burping system that prevents false priming due to possible water bubbles.

Small water leaks in the system after the pump, when the system is under pressure and without flow, can lead to a gradual drop in pressure. This will cause the pump to start up periodically, possibly causing damage to the motor, especially when starting at a short distance.

In this case, the electronics recognize the problem and activate the ANTICYCLING alarm. The alarm will prevent the pump from starting.

The alarm can be removed manually. The alarm would be removed automatically after 12 hours.
